Answer

$Ni(NO_3)_2+Na_2CO_3\rightarrow NiCO_3+2\ NaNO_3$ $Ni^{2+}(aq)+CO_3^{2+}(aq)\rightarrow NiCO_3(s)$

Work Step by Step

Balancing the sodiums: $Ni(NO_3)_2+Na_2CO_3\rightarrow NiCO_3+2\ NaNO_3$ Which is the fully balanced equation. Since nickel (||) carbonate is the only insoluble compound, the net ionic equation is: $Ni^{2+}(aq)+CO_3^{2+}(aq)\rightarrow NiCO_3(s)$
